ALTools
Loop Video
Repeat one clip 2×–10× for signage, product demos, or social backgrounds. Export a single longer MP4 locally in your browser — short jobs finish fast, large outputs stream straight to disk.
How to use this tool — step-by-step guideHow Video Looping Works
Upload MP4, MOV, WebM, or other common formats. Choose how many times the full clip should repeat (2×–10×), then export one longer MP4. ALTools processes everything locally — no upload and no account.
Product demos, waiting-room signage, landing-page backgrounds, and social B-roll often need the same short clip to play twice or more without manual timeline editing.
Looping is not a crossfade tool — the end of the clip jumps back to the start. Best results come from footage that already looks continuous at the cut point.
Small jobs can finish quickly when streams are copied without re-encoding. Very large sources or long repeated exports stream directly to the save location you choose.
Output duration and file size grow with each repeat. Start from a short source when possible, and leave enough free disk space for the finished file.
Download the looped MP4, convert to GIF with Video to GIF for chat formats, or Merge Videos if you need different clips in one timeline.

Frequently Asked Questions
Does looping create a seamless crossfade?
No. The tool repeats the full clip back-to-back in order. For a smooth endless loop, start with footage that already matches at the first and last frame.
How is this different from Merge Videos?
Loop Video repeats one file multiple times. Merge Videos joins different files in the order you arrange. Use loop when you want the same clip again; use merge when each segment is different.
How long is the output?
Output duration equals your source length multiplied by the repeat count. A 10-second clip at 5× becomes about 50 seconds. File size grows by roughly the same factor.
Do large files download differently?
When the source is large or the estimated output (source size × repeat count) reaches about 1 GB or more, the tool may ask you to pick a save location and stream the result straight to disk so the finished file does not have to sit entirely in memory.
Should I start from a short clip?
Yes when you can. Shorter sources finish faster and use less memory. Trim unwanted sections with Trim Video first, then loop the part you need.
Is my video uploaded?
No. Looping runs locally in your browser.
